A film based on Italy's bank scandal, which spread all the way to the Vatican during the 1980s, could be pulled from cinemas over claims it slanders an Italian businessman.

God's Bankers (I Banchieri Di Dio) is based on the death of financier Roberto Calvi, who was found hanged from a London bridge in 1982.

But lawyers for businessman Flavio Carboni says the film is "harmful" to his reputation.

Judge Marzia Cruciani said she will put a temporary ban on the film - provided that Mr Carboni puts up a 1.5m euro (£919,000) deposit to cover the movie's losses in case her eventual ruling rejects his case.
